I think #1 is a Social Flycatcher (Myiozetetes similis), might also be a White-ringed Flycatcher (Conopias albovittatus), but I tend to Social Flycatcher. The beak would be bigger in Great Kiskadee.#3: Could it be that this one is a different one? I tend to Tyrannus melancholicus, Tropical Kingbird, due to the grey head. But it is not easy to see in this perspective. Please, check or wait for confirmation by Liam.@Liam: It is your turn ;-)...
